Answer this question truthfully
### Question: What are the symptoms of Hearing loss in infants?
### Response: Signs of hearing loss in infants vary by age. For example:
A newborn baby with hearing loss may not startle when a loud noise sounds nearby. Older infants, who should be responding to familiar voices, may show no reaction when spoken to. Children should be using single words by 15 months, and simple 2-word sentences by age 2. If they do not reach these milestones, hearing loss since infancy may be the cause.
Some children may not be diagnosed until they are in school. This is true even if they were born with hearing loss. Inattention and falling behind in class work may be the result of an undiagnosed hearing loss problem.
